Adjustable Bag Handling Device with Dynamic Holding Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling flexible bags struggle to adapt to bags of different dimensions efficiently, as they require complex adjustments to accommodate varying widths and heights, which complicates the process of opening and closing bags for filling and sealing.
Innovation Solution
The device incorporates an adjustable holding distance between holding devices and a support framework with side and bottom supports that can be adjusted relative to each other, using a row of holes with a locking element for graded adaptation, allowing for easy adjustment to different bag dimensions. This includes clamps that clamp the lateral areas of the bag and a control mechanism for opening and closing, with a telescopic adjustment device that changes the relative positions of the holding devices to accommodate various bag sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the device uses fixed holding devices with fixed support framework, then the structure is simple, but it cannot adapt to bags of different dimensions
Solution Approach 1:
The patent applies the dynamics principle by making the holding devices and support framework adjustable rather than fixed. The holding devices can be repositioned along the conveying direction to accommodate different bag widths, and the support framework's side and bottom supports can be adjusted relative to each other to adapt to different bag heights. This dynamic adjustability resolves the contradiction between adaptability and structural complexity by allowing the same structure to serve multiple bag尺寸 through simple reconfiguration.
Solution Approach 2:
The patent applies segmentation by dividing the support framework into separate adjustable components - side supports and bottom supports that can be independently positioned. The holding devices are also segmented into multiple positions along the conveying direction. This segmentation allows each component to be adjusted independently to match different bag dimensions, achieving versatility without requiring complete structural redesign.
2Adaptability or versatility
If the device is designed for specific bag dimensions, then the structure is simple, but it cannot handle bags of varying sizes
Solution Approach 1:
The dynamic adjustability of the holding devices and support framework allows operators to easily reconfigure the device for different bag sizes by moving components to predetermined positions, simplifying the adjustment process while expanding handling capability.
Solution Approach 2:
The patent incorporates predetermined adjustment positions along the conveying direction and pre-configured support framework positions. These preliminary prepared positions allow operators to quickly switch between different bag sizes without complex calculations or custom positioning, improving ease of operation while maintaining versatility.
3Adaptability or versatility
If the holding devices are positioned far apart, then wider bags can be accommodated, but the device cannot handle narrower bags effectively
Solution Approach 1:
The holding devices are designed to be dynamically repositionable along the conveying direction, allowing the distance between them to be adjusted. This dynamic positioning capability enables the same device to accommodate both narrow and wide bags by simply changing the spacing between holding devices, achieving width adaptability without adding complex adjustment mechanisms.
Solution Approach 2:
The holding devices serve multiple functions - they can be positioned at different spacings to handle various bag widths, and they also provide support during the opening and closing operations. This multi-functionality allows a single adjustable component to replace what would otherwise require multiple fixed configurations, reducing overall device complexity while expanding capability.
